According to my understanding, governmental economic planning or may be called socialism.
Economic system of socialism. As the economic system of various economic units act, that is, the state will determine plan that society will need to produce goods and services is about how much? How to produce?. So, The country's economic decisions that apply this system comes from the decision of the Government or the centralized planning.
Economic system of socialism, the private sector has the right to private property holding just a little. Economic decisions came from the decision of the government or central planning. And the opportunity to expand production or improve production quality is going to be difficult as well.
